Mounting the base - ATN Quick Detach Scope Mount

When i went to mount the base on the optics rail of my AR the screws that clamp it on are left hand thread.My torque wrench only works on right hand thread,so i could not torque the screws.since it is a quick mount,torque setting are critical. The screws for the ring clamps are hex instead of torx and my master torque wrench set did not have a hex,no big deal,i'll just have to get one that fits.
